SYNOPSIS
     volatile

DESCRIPTION
     volatile is a compiler directive that causes the variable(s) associated
     with it not to be affected by the optimizer; that is, memory accesses
     will be done, in the coded sequence, even if they appear to have no side
     effects. Pointers to device registers should always be declared volatile.

   Return Values
     None
